Answer: (7x^2+144)/x^2

Step-by-step explanation:

f(h(x))=

f(12/x)=

(12/x)^2+7=

12^2/x^2 + 7=

144/x^2 +7=

144/x^2 +7*x^2/x^2=

144/x^2+7x^2/x^2=(7x^2+144)/x^2

Solve the system of equations x=y-4

Illusion [34]

Answer:

(-(23/3), -(11/3))

Step-by-step explanation:

x=y-4

2x-5y=3

=====

2x-5y=3

2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]

2y - 8 -5y = 3

-3y = 11

y = -(11/3)

y = -3 2/3

Use this in the 1st equation to find x:

x=y-4

x=-(11/3)-4

x = -(11/3)-(12/3)

x = -(23/3)

x = -7 2/3

See graph attached.

A manufacturer producing a new product, estimates the annual sales to be 9,600 units. Each year, 8% of the units that have been

Crazy boy [7]

Answer:

After n years, 120,000(1 - 0.92ⁿ) units, will be in use.

Step-by-step explanation:

Given;

estimated annual sales, a = 9600 units

determine common ratio, r;

$r = 1 - \frac{8}{100}\\\\r = 0.92$

sum of the units in use after n years is calculated by applying sum of nth term;

$S_n = \frac{a}{1-r} (1-r^n)$

$S_n = \frac{9600}{1-0.92} (1-0.92^n)\\\\S_n = \frac{9600}{0.08} (1-0.92^n)\\\\S_n = 120,000(1-0.92^n) \ units$

Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.
